Description

International audience To understand the sailing performance of traditional canoes in Oceania, we replicated ten sail rigs and tested them in a wind tunnel. Measurements of lift and drag forces demonstrate substantial differences in their performance. At low heading angles, from about 30 degrees to 80 degrees off the wind, three sails (Massim, Ninigo, Santa Cruz) are remarkable for their higher efficiency. Three other sails (Tonga, Hawaii, Tahiti) are remarkable for their lower efficiency from heading angles of about 90 to 130 degrees. In between, four more sails (Arawe, Micronesia, Vanuatu, Marquesas) have roughly similar performance to each other. The ranking of these sails is followed by a description of their distribution with inferences on historical evolution of canoe rigs.
